Alm Female Weld Bung 8AN ORB

The MOROSO Aluminum Female Weld Bung 8AN ORB is a precision-engineered hydraulic fitting designed for welded installation in high-performance fuel systems, cooling circuits, and fluid transfer applications. This female O-ring boss (ORB) bung accepts 8AN (AN08) male connectors and is purpose-built for permanent mounting where vibration resistance and reliability are non-negotiable. The aluminum construction balances weight savings with adequate strength for automotive and powersports applications where fuel delivery integrity is critical.

The 8AN ORB connection standard ensures compatibility with industry-standard braided hose, hard-line fuel tubing, and component fittings throughout the performance automotive aftermarket. The female configuration accepts tapered male threads with an integrated O-ring seal, eliminating the need for separate sealing washers and reducing leak paths common in older JIC flare designs. Weld-on installation provides permanent, leak-free mounting ideal for race fuel systems, custom fuel rails, and fabricated tank applications where vibration and high-cycle stress demand absolute reliability. The natural aluminum finish resists corrosion in typical under-hood environments.

This fitting serves engine builders, fabricators, and performance enthusiasts who are integrating custom fuel delivery systems, upgrading stock fuel systems to handle higher flow rates, or building competition vehicles where fuel supply integrity cannot be compromised. Weld bungs are favored in sealed-tank applications and custom fuel cell installations where removable fittings would create unnecessary access points. The compact footprint and clean installation profile make it ideal for tight engine bays and fabricated fuel system layouts.

MOROSO is known throughout the automotive industry for precision fuel system components, and this aluminum weld bung reflects decades of OEM and aftermarket experience in high-reliability fuel delivery. Proper installation requires TIG or MIG welding to a clean aluminum tank or component; the bung accepts industry-standard 8AN male connectors once welded and cooled.
